Either you're not entering the code correctly, or the input file is
different to what you've shown us so far.
I think you need to send me a copy of the input file - or at least a
larger sample than we've had so far so we can see what we're dealing
with.
The code should be:
from __future__ import with_statement
from collections import defaultdict
from decimal import Decimal
atoms = defaultdict(dict)
with open("file1.txt") as f:
for line in f:
try:
n, pos, ala, at, symb, weight, rad, count = line.split()
except ValueError:
continue
else:
atoms[int(pos)][at] = Decimal(weight)
#modify these lines to fit your needs:
positionsNeeded = (8, 15, 21)
atomsNeeded = ("C", "CA", "CB")
for k, v in atoms.iteritems():
print k, "ALA C = %s CA = %s CB = %s" % tuple(v.get(a,"") for a in
atomsNeeded)
Check you've got the indentation (the spaces at the start of lines)
correct, exactly how it is above: this is VERY important in python.
